Jetboil Flash - update of a great piece of kit

Jetboil have had a lot of success with their Jetboil stoves, and now with several on the market and selling well they are looking for ways to improve designs, and lower the weight. The jetboil flash does 50% of that! 

First off in terms of weight it's no different to the original Jetboil PCS (now called Jetboil Classic). It's exactly the same weight, with exactly the same power output, and boil time. For those of you who aren't familiar with Jetboil, the concept of the system is a small, lightweight, efficient stove unit. It can boil water very efficiently and quickly (under 2 minutes). The stove unit attaches to the cup (called the companion mug), and makes a very stable unit. A number of accessories are available for the system including a hanging kit (which isn't brilliant), a coffee press, and a stabiliser set (included with the Jetboil Flash). The stabiliser consists of a small tripod type affair that attaches to the bottom of the gas canister to stop the stove from over balancing, the set also includes a metal attachment for the top of the stove that turns the Jetboil into a more traditional stove that can have a pan or mess tin on instead of the companion mug.

After you finish cooking you can pack everything away inside the companion mug which saves space, and means you aren't scrambling around for everything when you want to make a brew! 

So whats new with the Flash? The Flash has a couple of new features which I feel are a real improvement on the original PCS. The first change is the gas regulator valve on the side. On the PCS this was a small knob that could be really fiddly, especially in gloves. This has been changed to larger wire frame, glove friendly adjuster - a significant improvement on the original. The second (albiet minor) change is the lid and bottom cover - these have been adjusted to an opaque plastic, this is a useful change as you can look into the stove and see how you cooking is progressing. The third change is a good one - the igniter on the previous unit was quite far away from the burner, this meant that in wind you often had to result to the backup lighter to get it working, on the Flash the piezo igniter is closer to the burner which seems to provide a much more consistent ignition! The final change is the sleeve of the unit. The sleeve now features a heat indicator that turns yellow when the contents of the stove are hot, in practice this means you can keep the lid on the stove until the sleeve turns yellow, removing the lid then will reveal the boiling water, and because you had the lid on the whole time the efficiency is maximised.

Overall I'm happy with the Flash and glad I got one when my PCS needed replacing, don't go out and buy one if you have a working PCS, as the new features are that significant, but if you want a jetboil, definitely get this one over the Jetboil Classic! 

Jetboil really is one of my favorite pieces of kit, it's lightweight, it's efficient, and it does the job I want it to do quickly, no messing around! The flash is an improvement on the original and comes with the stabiliser (previously £15 with the PCS) so that's an extra bonus! Worth shopping around for too it can be found at prices between £60-£112 so a big difference between retailers! 

Jetboil PCS – The coolest stove out there?

Of this there is no doubt, but is it any good? I've had one of these for a while now, so I thought I might as well review it!

Now for those are you who aren't familiar with the Jetboil, let me explain;

The Jetboil is an ultra efficient, lightweight, cooking system. The stove is designed to take up as little space as possible in a rucksack by storage for all the components (including the gas canister) being inside the cooking pot. At the moment there are 3 Jetboil systems on the market;

Jetboil PCS (Personal Cooking System)
Jetboil GCS (Group Cooking System)
Jetboil Helios

The PCS and GCS are designed to be modular, by this I mean if you purchase a PCS, you can buy additional components to have a GCS as well. The main difference between the GCS and PCS is the type of pot used for cooking. The PCS uses a 1 litre companion mug, where as the GCS uses a 1.5 litre cooking pot. Both systems uses the same burner self igniting burner system which is compatible with screw top canisters. The GCS also features a stabiliser kit so that the unit can be a standalone stove and will have additional stability on the floor rather than just the base of the gas canister. Essentially though if you buy a Jetboil PCS, you can buy a stabiliser kit and a 1.5 litre pot and have a GCS as an additional option.

On to the review. . .

I bought this stove to use when I am short expeditions. It appealed to me because it was efficient, light and easy to use. My stove combination consists of the Jetboil PCS and the stabiliser set, along with a gas canister this weights in at 670g. The addition of the stabiliser kit means my stove is more "team friendly". Without the stabiliser the Jetboil can only be used the jetboil accessories, by carrying the stabiliser kit I can share cooking with other team members as the kit converts the stove into a more universal setup (see pic)





I did a quick test to check the units specs listed on the website:
The stove should be able to boil water in 2minutes (0.5L), and boil around 12 litres per 100g canister. I bought a new canister and boiled as many 0.5L cups as possible, whilst averaging out the time taken on each. The average time taken to boil 0.5L of water was 1min 53.4secs, and I got 17 Litres of water from a single canister. Personally I think this is excellent for a small canister. All Jetboil pans use Jetboils patented Fluxring technology to increase efficiency, it functions in the same way a radiator works, by providing a larger surface area to heat up while cooking, as a pose to the flat bottom of a pan or mess tin. The same system is used on the 1.5L pot, 1L mug, and Frying pan.

In terms of cooking with the Jetboil a lot of people have said you are fairly limited in what you can cook. You can cook any kind of ration pack style meals. This just involves rolling the meal up and cramming it into the cup! Other than that anything that you would cook on a hob you can cook on the PCS. Which is ideal for short term expeditions.

The Jetboil is very well thought out, after you have finished cooking there is a plastic cover to protect you from burns while you are eating. There is also a sewn handle on the companion cup so you can move around while the stove is cooking.

In additional to being quite stable when fitted with the stabiliser kit, the stove is also fairly windproof, and is fitted with a small piezo electric igniter meaning there is no need to fiddle with matches in poor conditions.

Drawbacks? Well I'm yet to find one, however I have enjoyed shooting down some common Jetboil gripes lately which I thought I'd share....




Moan: "You can't cook big meals like you can with other stoves"
Owning: Purchase the 1.5 Pot, or purchase the stabiliser kit and a mess tin so that you can switch to that when you are out for longer

Moan: "The cartridges are so small"
Owning: Purchase a bigger screw seal canister....Idiot

Moan: "You have to hold it while it's cooking"
Owning: Put it down? Or better still buy the stabiliser kit and put it down


. . . You get the idea, any other gripes feel free to email me for an owning...


In addition to the various components in the GCS and PCS, there are a number of other accessories to customise your Jetboil kit:

Coffee press (£17.50)- turn you Jetboil into a coffee brewer
Frying pan (£44.99)- Fluxring frying pan, for efficient frying of tasty goodness
Hanging kit (£27.50)- a kit for handing your jetboil when big wall climbing, snow holing or whatever other use you could think of!
Jetboil cutlery (£13.50)- Highly temperature resistant nylon cutlery, light and tough, personally I'll stick with my titanium spork!
Additional coloured sleeves for companion mug are also available for further customising of your set (£5.99)


All in all you can't go wrong with a Jetboil, brilliant, customisable, efficient, not overly cheap but consider it an investment! RRP is £85, but browse around and you can get one for around £60! Stabiliser kit around £17.50 is also a must have!
